PROTECTING-COVER oe PNEUMATIC TIRES.

To all whom; it may concern:

Be it known that we, EUGENE BARDOU and LOUIS CLERO, residing at -12 Boulevard Se bastopol, and BERNARD Drisoucnns, residing at 16 Quai de Bethune, Paris, France, citizens of the Republic of France, have invented certain new and useful Improvements in Protecting-Covers for Pneumatic Tires; and we do hereby'declare the following'to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to figures of reference marked thereon, which form a part of this our invention is to provide an improved cover capable of protecting the pneumatic tire ona vehicle-wheel, so as to preventinjuries to said tire and avoid skidno- It consists in attaching onto an annular band made of a supple material, as fabric or leather, a tread formed of vegetal fibers,

horsehair, or other fibers twiste into cords of any convenient size, which'may then beassembled to make cables, said cords or catread ought to bles being afterwardunited'together either v by entwining or plaiting them or by passing yarns or wires transversely through them.

The cover is provided at its edges with eyelets, hooks, or other means for lacingthe cover on the tire and the felly of the wheel or with stra s and bupkles for the same purpose. The fi rous pad which constitutes. the e. comparatively narrow for instance, three inches in widthso as not to form any thickness on the sides likely to hinder the movement of the. driv' chain or band in the case of motor-cars. V thifiker at the middle part than at the e ges.

soaked in tar-pitch, rubber solution, or some other'adhesive material in order, first, to fill the spaces between the cords or cables, and, secondly, to cause the gravel to adhere to this pad, so forming a hardened surface,

7 which nevertheless does not affect the flexibilityof the cover.

In the drawings, Figure '1 is a, perspective view showin our improved cover in position on a tire an wheel. Figs. 2 and 3 areface views showing portions of a cover to illustrate different manners of forming the band or base to which the tread is attached.

reference such fibrous pad should be and a pad Patented may 29, 1906.

On Figs. 1 and 2 the tread 1 is constituted by a flat braid put on the backing orv base 2 edgewise and spirally wound .around the latter. f

On Fi 3 the tread is made up of cords or braids p aited together, the plait being laid flat on the base.

The tread is attached to the backing 2. I

either'bysewing or by'means of rubber solution, or both.

On Fig. 1 the backing 2 consists of a band of a very strong fabric, the two ends of which are connected together by any proper means for instance, by sewing offiriveting. Each edge of this band isstren t ened by a strip of-fabric or leather 3 an is provided means to attach the cover on the tire by lacingas, for instance, with eyelets 4 as shown. By preference the band 2 is curved in crosssection, so as to avoid creases. The band2 may also be made of lighter fabric and be strengthened by bands of leather 5, extendshown on Fig. 2. Inthis ca'sesuch bands of.

leather are lhdented to avoid creases, the

eyelets 4; being insertedin the tongues or wide parts-6.

In the modification shown by Fig. 3 the leather tongues 6, in which the eyelets 4 are inserted, are not backed with fabric in-o'rder.

to make the cover still li ht'er. Of course the base 2 o the tread might be wholly made of leather or fabric. Also the from each edge thereof to the tread, as

tongues 6 on the two edges might not be opposite each other.

What we claim as our invention, and 'desire to secure by Letters'Patent, is-- e 1. "A protecting-cover for neumatic tires composed of a flexible ann arbase, means for attachin such base on thetire and wheel, and a pad 'ed' onto said base at the tread .and made of 'fibers twisted into cords which are then united together.

2. A protecting-cover composed .of a flexible an ar base, means for attachin such base onthe tire and Wheel, ed onto said base at the tread and made of fibers twisted into cords which are then united together andcoated with an adhesive material.

' 3. protecting-cover for pneumatic tires composed of a flexible annular base indented on 1ts edges, means for attachin" such base for ne'umatic tires on the tire and wheel, and a pa fixed onto said base at the tread and made of fibers Q I seem? gether.

' 4. A protecting-coverfor pnehmati'ctir'es com osed of a flexible annular base strength--- ene at the edges, means on said strengthened edges for attaching such base on the tire and wheel, and a ad fixed onto said base at'the tread and ma e of fibers twisted into 'cords which are then united together, 1

5. A proteetin eggtver for pneumatic tires composed of a e 'ble annular base, the edges of which. are strengthened. and formed with indentures between which tongues are left to which eyelets are fixed for attaching" such base on the tire and v vheel bylaeing, and I 5 a pad fixed onto said base at the tread and made of fibers twisted into cords which are then united together and coated with an adhesive materia In testimony that we claim the foregoing 20 as our invention we have signed our names in presence of two subse'rlblng wltnesses.
